The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
Inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard.
SONIC-REBOUND TECHNOLOGY integrates R.T.C with high resilient modulus graphite material to enable swift and all-around rebound performance, redefining what a SPEED racket could be.
The Whipping Enhancement System incorporates a softer material in a specific part of the shaft near the throat, enhancing racket-head acceleration in a “whipping” style which helps to create steeper and quicker attacks with satisfying control.
Configure and combine white wood, carbon fiber, and resin through foam moulding technique, creating a standardized design. This newly developed material can effectively increase precision, weight, and performance without the tendency to absorb water and deform, enabling better hitting experience and stability.
The compound frame design can be divided into three major parts: The upper section is made with fan-shaped structure to lower wind resistance and accelerate each swing. The Compound-Sword structure in the middle section is designed to lighten the filler and enable fast rebound. Finally, the lower section is built in airfoil structure to lower wind resistance and keep excellent anti-torsion performance in a 'whipping' style which helps to create steeper and quicker attacks with satisfying control.
